Good sub (or subs) for around 300$

[j4tk]

Hi. Im new to the forums, well posting, and was wondering a good sub for around 300-350$. I have a 1997 Mitsu Montero, with third row seats out. I use yo have 2 pioneer champion pro 12, but sold them. Now I want back in the game. Was thinking Maybe 2 15s or a single 18. I have a hifonics 2500.1 amp. I'd be using it for daily use and

alright, trust you over myslef. new to all this. and on the subs. If i had the space for the 18 Obsidians, would you recommend those over the hdcs315s?

Yea if u got room go with the 18s just on cone area advantage

And I can put the 2500 watts between them both?

Most likely not the whole 2500 rms anyway. Alt doesn't charge fast enough.

In that price range id look at the obsidian 18s...do you have 12 cu ft after port and sub disp to work with?

Would this be enough?

L:52 (This is with no passenger seats)

W:31

H:23 ( can be more, that's just below the where the window begins.)

thats 24 cubes

With mu backseats down. The dimensions would be: L:3' W:3' H:2' 18 cube ft.

If you want to use 24 cu you could run 4 18's or a bunch of other choices like 8 sq hd212's with a large port.

I would, only if I had the funds. really can't go more subs. I'd need an extra alt and another battery. Plus true 0 gauge. I have that soundquest sheet.

Stick with 2 sq hds315's and do a 4th order bandpass they will do great in one.

So no to the obsidian 18s?

and on the bandpass box, how much would that cost? I was just planning on building a simple box. Mostly because of my budget, which isnt very much.

Obsidians work well in bandpass but the hds315 has a larger coil and will take the power better. You can build a 4th order there not that hard. I did a blow thru in a Buddy's s10 with a pair of 12type R's and it sounds amazing clamped only 726w. There are a few people on here that can design you a box and cut sheet. Suggest a 3to1 ratio tuned at 47-48hz.

why that tuning? I was thinking 30-32hz.

And yeah, my stepdad said bandpass boxes are the ****.

what all i really want is to be heard before im seen.

 

[j4tk]

I think im just going to go with the 15s because they are cheaper. the obsidians would be about 440 and the hds' aee 289

Bandpass boxes are supposed to be tuned high like that. The one I built was tuned at 47 and had a 4to1 ratio it was very strong from 30 to 45 hz and had decent output down to low 20's. The higher the ratio the more efficient but narrower bandwidth so a 3to1 tuned to 48 should do mid 20's to 50hz strong and peak in upper 30's. Trust me I'm running 2 15's on 5k and I was very surprised by the output of the type R's on so little power. I would do a 4th but mine are not very good for 4ths.

ah, alright. gotcha. You know anyone in particular that makes the bandpass'?
